A wakefulness-promoting agent, or eugeroic, is a type of drug which specifically improves wakefulness and alertness. They are used mainly in the treatment of sleeping disorders, excessive daytime sleepiness and narcolepsy.[medical citation needed] They are also used merely to counteract fatigue and lethargy and to enhance motivation and productivity.[medical citation needed] Wakefulness-promoting agents appear to function primarily by increasing catecholaminergic (adrenergic, dopaminergic), histaminergic, and orexinergic activity in the brain. Unlike many other stimulants, wakefulness-promoting agents are relatively non-addictive and non-dependence-forming.
The prototypical eugeroic is modafinil, and other drugs include adrafinil and armodafinil. The primary difference between these drugs and amphetamine-like stimulants is that wakefulness-promoting agents specifically trigger activation of neurons in the hypothalamus-based wakefulness circuits, as opposed to producing diffuse neuronal activation.
